About ECOG Score Calculator

ECOG Score Calculator is a clinical tool used to measure a patient’s level of functioning and ability to carry out daily activities, particularly in oncology. It helps clinicians assess how a disease—especially cancer—affects a patient’s quality of life and tolerance to treatments like chemotherapy.

Score Categories:

  • 0 (highlighted in green) – Fully active, able to carry on all pre-disease activities without restriction.
  • 1 (highlighted in green) – Restricted in physically strenuous activity but ambulatory and able to perform light work.
  • 2 (highlighted in orange) – Ambulatory and capable of all self-care but unable to carry out any work activities; up and about more than 50% of waking hours.
  • 3 (highlighted in orange) – Capable of only limited self-care; confined to bed or chair more than 50% of waking hours.
  • 4 (highlighted in red) – Completely disabled; cannot carry out any self-care; totally confined to bed or chair.
  • 5 (highlighted in red) – Death.

The ECOG score is commonly used in cancer trials and treatment planning to determine patient eligibility and predict tolerance to therapy.

Our calculators apply published formulas as precisely as we can. Even so, no formula captures every detail of a real patient. Use the result as one input to your own assessment, not the final word.
